CEMENT FORM.`

Applicationvled June 6,

The object of my invention is to provide new and useful` improvements in Aaf cement form of simple, l durable,v and inexpensive construction. Y f

A further object of' my: invention"v is to provide a multiple block moldf by which a .4 t y n king wheels 1l designed tol runon rails 12v pluralityv ofv concrete blocks may be made at the same time in the same mjold. j

further object of my invention. isl to` pro-` vide a'multiple block mold which. is partiewk larly adapted for making slush concrete blocks as distinguished from the blocks made s byA the semi-dry method. f

A furtherobject of my Vinventiongis to provide a multiple block mold havingcol lapsible cores by which the blocks maybe made with hollows or `air passages `therein conveniently 'and "expeditiousl l A 'further object of my vinvention isto provide a peculiar typel ofcore whichwill ycollapse or expand in the direction of both l gi'tudinal partition vmembersl vto anchor transverse dimensions. f

A further object of mylinvention is to pro-V 1 `vide a multiple block which is so constructed that-the individual" 'blocks made thereby may be formed on independent pallets lso that the blocks may be conveniently handled after being removed from lthe molds vand during the soned. i' s Y t With these land other lobjects* in view, my V invention .consists in the arrangement, com- `binatiorn"and Vconstruction, of the yvarious' parts of my improved device, as described' inA the specification,` claimed fin' my claim,` and shown in the accompanyingdra'wings, in which: -w

Referring to: the accompanying drawings,

I lhave shown the multiple mold as being mounted lon Vaftruck having a platform l?)y which vin turn is mounted on a truck havand provided 'with side lmembers or stakes Thestakes 13 `at one sideof the truck yare beveled on their inner'surface to coact .of a' plurality oflongitudinal partitions 15.

csf

whichare held in position 'spaced from each `otherby ,a plurality of transverse-=partition members,16;.v These transverse members 16 have `tongues 17 at one, vend andv pockets 18y at theother end whereby the tongue 17 may befpassed through the yslots 19 in the lonthe vtransverse Vmember 16,- from' movement relative to the longitudinal partition memother Y v Y The transverse partitionmembers 16 fare preferably formedfr'om three superimposed strips of sheet metal which have theiredgesfastened-together by the vcountersunk rivetsv illustrated inF-igure 10. The central strip f `or from movement relative to each isformed to make the tongue 17 andthe pocket .18.. The longitudinal members 15 yshapeof substantially a parallelogram and` which are foldedv adjacent to each edge to vform aV flange 25. One ange of each strip e have a, plurality of pairs ofadjacent openings 23 therein softhgat when the longitudin-n is yprovided with a pair of slots 27 and the other flange is providedwith a pair of but'- tons 28` so that when the rfo-urstrips .are

folded on adiagonal line substantially bisecting the strips, then that Vthe buttons on one `iange will enter the slots in the flange angle irons 30 which are secured to the lower rolled orp'tamped to initially set same. InV

surface thereof by a plurality of countersunk rivets 31 or preferably by spot weld` m0'.

zln the practical operation of my improved device the' moldis assembled on the truck member by first placing one longitudinal member 15 against the stakes 13at one side of kthe truck which have the vertical inner surfaces. A row of transverse members 16 is then placedl against this iirst longitudinal member 15 and the pallets 29 for the first row of blocks are then placed onthetruck. A second longitudinal member 15 may now be assembled on the 'projecting tongues 17 ofV the transverse members and a second set.

of transverse members 17 and pallets 29 placed on the truck. This process is continued until the entire five rows of molds are completed and then when the last longitudinal member 15 is installed, wedges 14 may be driven down between the stakes 13 having the inclined inner surfaces and the last longitudinal member 15 to lock the mold from movement. The core members illustrated in Figures 4 and 5 may now be installed by collapsing these core members and inserting them'in the holes 23 in the longitudinalmembers. After being placed in-these holes the core members are expanded by pounding the ends thereof until all four sections thereof are properly seated against'the openings 23.

Slush concrete may now be poured over the mold to fill the various block forms` therein and'if desired the concrete may be 10 of the truck member so that they may be readily lifted therefrom to be placed on other trucks or suitable platforms for seasoning.

lith this improve-d mold l am able to make slush concrete blocks satisfactorily and with reasonable economy with the well known advantages of slush concrete as com-V pared with the semi-day method of making cement blocks.k p

mong the many advantages arising from the use -of my improved mold it should be specifically pointed outthat the mold itself is constructed from sheet metal which may vbe readily purchased in theV open market and very little forming or cuttingv of the metal is required in order to form these molds. Moreover the mold is easily assembled and disassembled, is comparatively simple, and the danger of cracking or in! `juring the completed blocks at the time of disassembling is comparatively slight.

1 claim asmy invention:

In a mold for a plurality of Vvconcrete blocks, a plurality of spaced longitudinal members having spaced slots therein and aL plurality of transverse members each composed of three strips of sheet metal, the outer strip being bowed to form corresponding hollows in the blocks and the central strips having` tongues formed at one end and pockets formed at the other end whereby said tonguesV may enter the slots adjacent thereto in the longitudinal members and the pockets in the adjacent transverse members to thereby lock the longitudinal mem-L bers from movement relative to each other and relative to the longitudinal members.
